To use codes, hold the ALT key on your keyboard and type numbers at the same time. Let go and you will see the accent appear on your screen!

If you are using a laptop, hold the blue Fn (function) key and the ALT key at the same time. Look for the blue keys with numbers on them and hold the key for that number. Make sure to not let go of the Fn key! Then let go and you will see your character.

For example, "J" has a small blue number "1" on it, and "K" has a blue number "2" on it and so on. You will see the rest of the blue numbers on the rows above each other.
